Any other information on results incl. tables
The pigment-solutions were not stable. After ca. one week an agglomeration of the pigment can be
observed (especially in water). So there are two different results given for this pigment.
One measurement was made immediately after filtraton of the pigment. The clear solution was
injected in the HPLC. The second measurement was made after one week. The solution shows an
agglomeration of the pigment. This pigment was filtrated again and the clear solution was injected
in the HPLC.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
